$str[1]="i我是一只小小qq:42343243 444234324"; $str[2]="我是一只小小qq联系人42343244234 fasdfdsfas"; $str[3]="我是一只小小qq42343244234 fasdfdsfas"; $preg="#(d*)(d{5,14})#"; for($i=1;$i<4;$i++){ preg_match($preg,$str[$i],$arr); echo "<pre class="brush:php;toolbar:false">"; print_r($arr); echo "<pre class="brush:php;toolbar:false">"; }
最简单的方法如下
preg_match_all('/(qq)+.*?(d{4,16})/i', $c, $strresult); int preg_match_all ( string pattern, string subject, array matches [, int flags])
在 subject 中搜索所有与 pattern 给出的正则表达式匹配的内容并将结果以 flags 指定的顺序放到 matches 中。
搜索到第一个匹配项之后,接下来的搜索从上一个匹配项末尾开始。
flags 可以是下列标记的组合(注意把 preg_pattern_order 和 preg_set_order 合起来用没有意义):
以上就是PHP的preg_match_all正则字符多次出现第一次出代码的内容,更多相关内容请关注PHP中文网(www.php.cn)!
